Robust Gain-Scheduling Control for Type 1 Diabetes Model with External Disturbance

We present a novel robust gain-scheduling control method for a type 1 diabetes model with external disturbance. Firstly, a type 1 diabetes glucose-insulin dynamics model is transformed into a continuous-time system with input saturation and external disturbance. Secondly, the robust gain-scheduling controllers are provided to ensure asymptotic stability of the closed-loop system, and the control gains can be easily obtained by solving several linear matrix inequalities (LMIs). Thirdly, the effectiveness of the proposed approach is illustrated by mean of a numerical example. The robust gain-scheduling control approach proposed in this paper can be used to control normal blood glucose levels.
